SIGN.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed. May 18, 1908. Serial No. 433,439.

T 0 all whom it may concern:

Be it known that I, FREEMAN E. CAY- WOOD, a citizen of the United Statesof America, residing at 580 Broad street, Elyria, in the county ofLorain and State of Ohio, have invented certain new and usefulImprovements in Signs, of which the following is a specification,reference being had therein to the accompanying drawings.

In signs for advertising and display purposes, of the type wherein bullseyes or jewels of translucent or transparent material are inserted inthe face of the sign, and especially where they are lighted from within,it is desirable that the jewels or bulls eyes be replaceable from theoutside without the necessity of disturbing the interior of the signs.The joint between the jewel, which is necessarily of somewhat irregularcontour owing to the impossibility of forming the vitreous material ofwhich it is made to exact size and shape, and the sign body or face alsomust be tight to exclude moisture from the lighting means in the sign,and to prevent rattling of the parts.

This invention relates to signs of this type and more especially tomeans for securing the jewels or bull's-eyes in place in such manner asto be readily removed and replaced from the outside without disturbingthe sign itself or getting into the interior, and for forming a closejoint between the jewel and sign body without the use of a gasket,packing strip, cement or the like.

The invention consists in the matters here inafter set forth, and moreparticularly pointed out in the ap V ended claims.

Referring to the crawings, Figure 1 is a view in front elevation of asign embodying features of the invention. Fig. 2 is a view in section online :ra; of Fig. 1. view in detail in perspective of a jewel or cupwith the adjacent portion of the jewel retaining plate or face of thesign in position for assembling. Fig. 4 is a view in section of thejewel and plate in assembled position, taken on or about line yy of Fig.3.

In the drawings, 1 indicates a hollow sign body or casing having adisplay side 2 of sheet metal on which character letters 3 or the likemay be painted or inscribed in any suitable manner. A series of circularapertures are formed in the sheet metal wherever it is desired toilluminate the sign surface. These each have three or more radialretaining lugs t struck out from the body of the Fig. 3 is ametal andslightly inbent toward the inside or back of the slgn, and a lockingfinger 5 diametrically opposlte one of the lugs, that is turned in thesame manner as the lugs but more acutely. A bulls eye or jewel 6 ofglass or like suitable material, preferably hemispherical or cup-shaped,has a circular collar 7 with outer peripheral rounded rib 8, preferablyhollow for lightness, that is adapted to be inserted through an aperturein the sign side, the rib having notches 9 which register with and allowthe lugs 4 to )ass through while the tongue 5 is forced back by the rib.A part turn of the jewel crowds the lugs yieldingly into the retaininggroove between the rib 8 and an annular shoulder 10 at the base of thecollar, and allows the tongue 5 to snap into one of the rib notches 9,thereby locking the jewel in place. The pressure of the yielding lugs onthe rounded rib forces the jewel inwardly so that its shoulder forms aclose joint with the side 2. By turning the notches of the rib back intoregister with. the lugs the jewelmay be pulled out. By thisconstruction, the necessity of an elastic gasket either for a tightjoint or to prevent rattling, is avoided, the spring lugs and fingerforcing the jewel and plate together and the thin sheet metal yieldinglyaccommodating itself to any slight irregularities which occur in thejewel, the material of which the latter is blown or cast precludingabsolute uniformity in size and shape. The joint thus made issufficiently tight without using cement or the like, and the jewelcannot rattle or work loose, and is readily withdrawn and replaced, ifdesired or necessary.

i lhat I claim as my invention is 1. A sign having a side of sheet metalprovided with one or more substantially circular apertures, inwardlyprojecting lugs a locking finger on. the aperture margin, and a jewel ofvitreous material having a circular collar adapted to engage anaperture, said collar having notches adapted to register with the lugs,and a retaining rim coacting with the lugs to crowd the jewel axiallyagainst the side when the jewel is inserted and the lugs turned out ofregister with the notches, the locking finger being adapted to engage arim notch when the lugs are out of register therewith.

2. A sign having a sheet metal plate with one or more circular aperturestherein, inwardly bent radial lugs integral with the plate on the marginof each aperture, a spring locking finger integral with the plate on themargin of each aperture, bent at an angle to the plate, and a jewel foreach aperture having a collar adapted to closely fit the aperture, aretaining rib on the collar having notches adapted to register with thelugs, and an annular shoulder at the collar base, the lugs bein adaptedto crowd the shoulder against the plate when turned out of register withthe rib notches between the rib and shoulder and the finger beingadapted to yieldingly engage one of the rib notches when other lugs areturned out of register therewith.

In testimony whereof I afiix my signature in presence of two witnesses.
